Try to imagine a clear sky. Only blueness over your head. Nothing more. However there is a sun there. Blindingly noticable. You hear no sound. No sound except the music of the open sky. You sit in your window. Listening to bamboo windchimes. You listen to the wind. Clouds give you harmonies. This is timeless. You listen until you sleep. You wake up to listen more. That open sky. It is fascinating.
